By grounding its ruling in the First Amendment and avoiding narrower ways of resolving the case, the US Supreme Court's holding in Citizens United has the effect of preempting state and local laws banning corporate expenditures, because of the application of the First Amendment to the states via the Fourteenth Amendment.
A grand total of 24 states
restrict OR ban corporate expenditures, with 22 banning and 2 restricting them.
Even though only 22 states ban corporate expenditures, 77% of those states have gubernatorial elections this year. Of the states that do NOT ban corporate expenditures, states banning corporate expenditures has a gubernatorial race this year -- in addition to House races for all positions. (The Senate 2010 election map is here:

In addition to the 17 banning, five other states ban such expenditures but do not have gubernatorial races this year. (See below)

Of all the gubernatorial Toss up states, all but 3 (Vermont, Nevada, and Florida) are in states that have corporate expenditure bans that have been nixed.
Outside of outright bans, New York (Blue-31 electoral votes, D-governor incumbent 201 election) and Alabama (Red-9 electoral votes) have
restrictions but not bans on corporate expenditures but do not have gubernatorial races this year.
The grand total of affected electoral votes are 132 Blue electoral votes and 92 Red electoral votes, including Texas's 34.
Of course, the elections for 100% of the House of Representatives in November of this year are all greatly affected, as well as 1/3 of the Senate.
